Prometheus raises $12B to build artificial general engineer

Researchers from NYU, Columbia, Princeton, University of Maryland, Harvard, and Lawrence Livermore National Laboratory published a paper introducing Latent Context Language Models (LCLMs), a compression technique that reduces LLM input by 16x while maintaining accuracy better than existing methods. Unlike KV cache compression, LCLMs compress tokens before decoder processing, delivering 8.8x faster output on long-context benchmarks. The models are open-sourced on HuggingFace and designed to integrate into existing LLM stacks.

Xiaomi has open-sourced MiMo Code V0.1.0, a terminal-native AI coding assistant that claims to outperform Anthropic's Claude Code on long-horizon, multi-step coding tasks (200+ steps) according to internal benchmarks. The tool uses a cross-session memory system with SQLite FTS5 to retain context across extended work sessions, addressing a core limitation of existing AI coding agents. Xiaomi is also offering limited free access to MiMo-V2.5, its flagship model with a million-token context window.

Microsoft has released SkillOpt, an open-source framework that automatically optimizes AI agent skills, the text-based instructions that guide model behavior in enterprise workflows. Unlike manual skill editing, SkillOpt applies deep-learning-style optimization to evolve skill documents based on performance feedback without modifying the underlying model weights. The tool addresses three recurring failure modes in skill optimization: lack of step-size control, absence of validation, and no negative memory to prevent repeated failed edits.

Snowflake is systematically deploying AI agents across internal business functions to automate routine work, from earnings call preparation to customer account analysis. The company uses its own products, CoCo and CoWork, to build these agents, reducing tasks that once took weeks to minutes. By operationalizing AI internally, Snowflake aims to improve both employee productivity and its ability to sell AI solutions to customers.
